In this study, a new chalcohalide glass system, Ga
2 S3 -Sb2 S3 -CsI, is reported. It has a glass-forming domain composed of ~0-35 mol% Ga2 S3, ~15-95 mol% Sb2 S3 , and ~0-55 mol% CsI. The glasses have a wide transparent window of ~0.7-13.5 μm, high third-order nonlinear refractive indices of ~1.7-8.7×10−14 cm2 /W @ 1.55 μm, and relatively short zero group-velocity-dispersion wavelengths of 3.8-5.15 μm. The glasses can dissolve more than 2 mol% active ions (e.g., Dy3+ ), and the doped glasses show intense emissions in the mid-infrared. These superior properties demonstrate their good potentials for mid-infrared applications such as thermal imaging, nonlinear photonics and lasers. [ABSTRACT FROM AUTHOR]- Published
